 (Billups, who has kindly presented the specimen to me), 

 and one <J, Chobham, Ist Aug., 1891, taken by myself. 

 These are the only three recorded captures of this 

 little insect in Britain ; either sex might be passed 

 over for a black Halictus, but the want of the third sub- 

 marginal cell will detect it. Its flight also is different,

 I caught for a second before it settled, I knew by its 

 wriggling flight that I had got something good, and sus- 

 pected Dufuurea at once. It must be an exceedingly 

 scarce insect, as I have looked for it carefully in my neigh- 

 bourhood every year since 1881, and have only seen this 

 one c?.
